What are the symptoms of a damaged outer CV joint in a car?

[MelanieDella]

The symptoms of a damaged outer CV joint in a car are as follows: 1. The main manifestation is the jamming of the steel balls, which results in a clicking sound (but this must occur under the condition of changing direction). 2. Another symptom is the crushing of the steel balls, which causes the engine's power to fail to reach the wheels, leading to slipping between the inner and outer parts of the CV joint. Without professional inspection equipment, the following parts of the car's CV joint should be checked: 1. The dimensions of the internal and external splines and threads, as these affect the installation size of the CV joint. 2. Check the size of the oil seal groove on the outer CV joint, as different models of CV joints may have varying oil seal groove sizes. 3. Verify whether the internal spline's retaining ring groove is correct, as the width of the retaining ring groove affects the axial movement of the CV joint on the half-shaft after installation. 4. Insert a shaft into the internal spline and wiggle the CV joint to check if it rotates smoothly. 5. Material and heat treatment properties require specialized equipment for inspection.
